D

Answer
dorsiventral leaf
Explanation
Solution
Transpiration is the evaporative loss of water by plants. It occurs mainly through the stomata in the leaves. Usually the lower surface of a dorsiventral (often dicotyledonous) leaf has a greater number of stomata while in an isobilateral (often monocotyledonous) leaf. There are almost equal number of stomata on both surfaces.
